I read an article in *Wired* magazine which indicated that for optimal battery life we should keep our laptops between 80 and 40%. The author decried the fact that they could find no app that would help us to follow this regimentation. They somehow missed *Juice!*. This is exactly what I needed for my new laptop. Now a pleasant voice tells me when to plug in and unplug my laptop. I kept my last laptop plugged in most of the time and it shortened it's life enormously.

I couldn't believe how unnoticable the stock low battery warning is on my new macbook. My last laptop was a PC and it had warning symbols and sounds that showed up in front of whatever program I used. When I started using my Macbook pro, you can't even see the battery bar in some apps so I was having unexpected shutdowns in the middle of image processing and losng files. Thank you. Thank you. Thank you. Thank you.

So simple and perfect. Tell me when the batter goes above x% or below x%. Other apps that just prevent the battery from charging above a certain level don't notify you at certain percentages like Juice! does. For me, this app is perfect for prolonging battery life by simply reminding my to unplug and plug in at 80% and 20% respectively.

I wanted an audio alert system to warn me of battery depletion on my Macbook Pro (Retina, 15-inch, Mid 2015; OS 10.14.6). The Macbook puts a discreet and silent notification in the upper righthand corner of the screen, which I have missed a million times and then the laptop just shuts off while your working. - Not cool. Juice! has a nice sounding female voice alert (in English language) that lets you know if your battery is getting low or if your power cable has disconnected. -Works perfectly.
